7 Claims.

This invention relates to sewing machines and more particularly to machines for sewing irregular, intricate and fancy designs in a fabric and for applying or attaching to such fabric, cord or wire encased in a tape or similar medium.

The invention has relation to the type of machine illustrated in the patent granted to me on November 28, 1933, No. 1,937,491, and the patent granted to me on February 13, 1934, No. 1,946,- 869, and has specific relation to an improved sewing head for carrying the cord or wire, together with the enclosing tape or similar medium, and for feeding the same simultaneously into association with the sewing needle which applies or attaches the cord or wire encased in the tape directly onto the fabric and in conformity with the outlines of a design.

An object of the invention is an improved sewing machine of the drum type.

A novel feature of the invention is an improved freely rotatable sewing head for carrying the cord or wire and enclosing tape and for feeding the same directly to the sewing needle and into operative association with the fabric.

Another feature of the invention is an improved means for attaching the sewing head to the machine.

Other features of the invention will appear as the description thereof progresses.

Referring to the drawings, the frame of the sewing machine is composed of end members l0 and H spaced apart from each other at the bottom by T-shaped. members l2, and at the top by a built up structural member 13. Also, extending between the end members In and I I is a structural member ll, while below such structural member is a second member IS on which is adjustably mounted a trackway l9 for a drum.

Mounted on the structural member I3 is the head I! to which my present invention may be attached. On the structural member I4 and directly beneath the head I! is the loop taking means including a housed bobbin l8 of the sewing machine. The head IT and the loop taking means l8 are driven in synchronism with each other from a motor l9 which operates a control device 20, and from which control device is operated the drive shaft 2| for the head I1, and the shaft 22 of the loop taking means I8. As a matter of convenience in the operation of the machine, the head is rotatably mounted as a unit in a bracket 23, secured to the structural member l3.

,The motor 19 is controlled at will by the operator through a treadle 24 secured to the rotatably mounted shaft 25 on the spacing and connecting members I2. The treadle 24 is located in front of and below the head I! as this is the place where the operator of the machine will stand while operating the machine.

The track for the drum to be hereinafter described is designated l6, such track It being mounted on the I-beam l5 and adjustable thereon to level such track 16 as needed. The track I5 is provided with a plurality of threaded holes along its length and on either side thereof and through which pass threaded bolts 26, such threaded bolts 26 being threaded into holes in the I-beam I 5.

Also, adjacent each of the threaded bolts 26 and in the top flange of the I-beam I! are two holes, each threaded-to receive the threaded bolts 21 which engage with the under face of the trackway l6, as clearly shown in Fig. 6.

By means of the bolts 26 and 21, the trackway l6 may be levelled regardless of whether or not the top flange of the I-beam is level, and when so levelled is maintained in such position by the bolts 21. This is important as the drum carrying the fabric in which the design is to be sewn is relatively heavy and must be easily movable to be accurately handled if the design is to be sewn accurately.

The drum comprises end spiders 28 each having a central hub 29 and an outer cylindrical rim 38. The spiders 28 are adjustably spaced apart from each other by means of telescoping members in the following manner. In one of the spiders 28 are secured a plurality of tubular members 3|, symmetrically arranged and secured to the spider adjacent the periphery thereof, and

xtending toward the other spider 28. Secured to the other spider 28 and symmetrically arranged thereon adjacent the periphery thereof and extending toward the first said spider are a plurality of tubular members 32. This structure is clearly shown in Fig. 4, and referring to such figure it will be noted that th ends of the tubular members 3| nearest to the other spider 28 are provided with internally threaded plugs 33, of substantially the same diameter as the internal diameter of the tubular members 32.

Also it will be noted that the end of each of the tubular members 32 adjacent the first said spider is provided with a cap 34 having a bore therethrough which is equal substantially to the outer diameter of the tubular members 3|. Secured in the end of each of the tubular members 32 is a plug 35 and in each such plug is rotatably mounted a shaft 36 provided with threads throughout the major portion of its length, which threads engage with the threads of the plug 33 secured in each of the tubular members 3 Each of the shafts 36 has one end 31 made non-circular to receive a wrench or other instrument by means of which the shaft 36 may be rotated. Also secured to the respective shafts 36 are sprockets 38, over which runs the sprocket chain 39.

As stated above, there are a plurality of tubular members 3| and 32, symmetrically arranged about the spiders 28 adjacent to the periphery thereof, and naturally each of the shafts 36 associated with the tubular members 32 is provided with a sprocket wheel 38. On two of the arms of the spider 28 carrying the tubular members 32 is a bracket having thereon stub shafts 46, and on such stub shafts are rotatably mounted the idler sprockets 4|. The sprocket chain 39 is endless and as viewed in Fig. 2 passes over the plurality of sprockets 38 and over the sprockets 4|. It will be apparent, therefore, that by placing a wrench or other instrument on the non-circular portion 31 of one of the shafts 36 that such shafts may be rotated in either direction, to thus extend the tubular members 3| and 32 with respect to each other, or telescoping the same, to thus move the spiders 28 further apart or closer together respectively. Also, it will be apparent that this expanding or contracting action of the tubular members 3| and 32 takes place simultaneously at each and all of the said tubular members.

The spiders 28 have formed integral with the hubs 29 thereof spaced bearing members 42. In the ends of the spaced bearing members 42 are respective stub shafts 43, and on each of the stub shafts is rotatably mounted a roller 44, such roller 44 engaging with the trackway l6. By this means the spiders 28 and tubular members 3| and 32, constituting the drum, may be moved along the trackway l6 and thus be moved relative to the sewing head |1.

Formed on the outer periphery of the hub 29 of the spiders 28 is a circular track 45. Fitting over th track 45 in the hub 29 is an annular member 46 provided with spaced symmetrically arranged radially extending pockets 41 about the periphery thereof. Rotatably mounted in the annular member 46 at each of the radially extending pockets 41 is a shaft 48 adjustably secured in rotative position by the set screws 49. Formed integral with the shaft 48 and eccentrically mounted with respect to the axis of said shaft 48 is an eccentric portion 58 of shaft 48 on which is secured the inner member 5| of a ball bearing, the outer member 52 of which rolls in the track 45. By means of the shaft 48 the roller bearing above referred to may be so adjusted with respect to the track 45 that the annular ring 46 will rotate on the track 45 without appreciable play.

Formed integral with the annular members 46 and diametrically arranged with respect thereto are th arms 53 and 54 respectively. The ends of the arms 53 are connected by telescoping tubular members 55. The details of construction of the members 55 are not important. Such members resemble in some degre the members which connects the ends of the arms 54 to be later described in detail.

The rims 56 of the spiders 28 have secured thereto respective annular members 51 which are bearing race rings. Each bearing race ring 51 has an extension 58 which lies at substantially right angles thereto. Associated with each bearing race ring 51 is a ball bearing retaining ring 59. Spaced about each ball bearing retaining ring 59 and extending therethrough, parallel to the axis of the corresponding bearing race ring. are bearings, in each of which is mounted an adjustable bearing shaft 60. The ball bearing retaining rings 59, at each of the bearing shafts 66. are provided with respective radially extending slots, in which are mounted respective ball bearings 6|. The inner members of the respective ball bearings 6| are mounted on respective eccentric portions 62 of the respective shafts 60, and the outer members 63 of the respective ball bearings 6| engage with the bearing race rings 51, as clearly shown in Fig. 4.

Enclosing or surrounding the ball bearing retaining rings 59 are respective drum rings 64, pro vided on their inner peripheries with respective bearing races 65, with which engage the outer portions 63 of the ball bearings above referred to. By properly rotating the respective bearing shafts 68, the eccentric portions 62 thereof are utilized to adjust the ball bearings, relative to the respective ball bearing race rings 51 and bearing race rings 65. When in proper adjusted position, the bearing shafts are clamped in position by the set screws 66.

The drum rings 64 have respective inwardly extending rings 61 on their inner faces to which are secured respective bearing race rings 68, which lie opposite to and spaced apart from corresponding race rings 69, formed integral, respectively, with the perpendicular extensions 58 of the bearing race rings 51.

The ball bearing retaining rings 59 are provided with respective sets of spaced perforations extending radially therethrough, in each perforation of which is adjustably and rotatably mounted a bearing shaft I8, such shaft being provided intermediate its ends with an eccentric shaft portion H, see Fig. 7. At each of the shafts 18, and extending laterally through the ball bearing retaining rings 89, are slots or openings 12, in which are housed ball bearings, the inner portions I8 of which are respectively mounted on the eccen tric shaft portions II, while the outer portions 18 of which engage with the bearing race rings 88 and 88, respectively. By properly adjusting the bearing shafts 18, the outer portions I8 of the ball bearings are adjusted relative to the bearing e rings 88 and 89. Such shafts are held in adjusted position by means of the set screws 15.

Secured to the outer peripheries of the drum rings 88 are respective clamp rings 18 which clamp respective strips of fabric 11 securely in position on the drum rings. n the free edge of each such fabric strip I1 is the zipper element I8 which cooperates with a like zipper" element 18 secured to an adjacent edge of a fabric strip 88. Such fabric strips 88 are sewn to opposite edges of the fabric 8| on which it is desired to sew the designs or pattern.

After the strips of fabric 88 have been sewn to the fabric 8|, the several zipper elements 18 and 18 are brought into engaging relation above the periphery of the drum rim 88. The shafts 88 are then rotated in the proper direction to extend thetelescoping members 3| and 32 until the entire surface of the fabric 8| is stretched taut.

Mounted on the structural member I8'and extending transversely thereof is a plate 82, see Fig. 12. Slidably mounted on the plate 82 and spaced apart from each other are brackets 83. Secured to the brackets 83 are the ends of a circular ring or hoop 88 of flat metal. The ring or hoop 88 extends around the structural member and the I-beam 5 and'is adjustable in diameter. Secured to the under face of the I-beam is a bracket 85 to which the ring or hoop 88 is secured at its lowermost point. Pairs of bearing members 88 and 81 are mounted on the Plate 82 and in each pair is rotatably mounted threaded screw shafts 88, one of such screw shafts being threaded righthanded and one lefthanded. The screw shafts 88 engage with threaded holes in the brackets 83. v

To the inner ends of the screw shafts 88 are secured bevel pinions 89, which mesh with and are driven by a bevel pinion 98, secured to a shaft 8|, one end of which is rotatably mounted in a bracket 82 secured to the plate 82. The shaft 9| extends along the top of the structural member I8 to a point adjacent one end thereof and is provided with a bevel gear 93 which meshes with a corresponding bevel gear secured to the lower end of a shaft 98 and which shaft has at its upper end a bevel gear 95 which meshes with a bevel gear 98 secured to one end of a shaft 91. rotatably mounted in suitable bearings attached to the spacing member l3. wardly to a point adjacent the sewing head I1, and is driven from a crank 98 through suitable bevel gearing, so that the operator by rotating the crank 98 may move the brackets 83 toward or away from each other to thereby expand th diameter of the rin or hoop 88 until the intermediate portion of the fabric 8| is held in position with respect to the bobbin holders and sewing head ll of the sewing machine.

The shaft 91 extends 111-.

The arms 88 are each provided with a-laterally extending member 88, and to each said member is pivotally mounted a lever I 88. The arm of the lever I88 adjacent the arm 88 is plvotally at-- tached to one end of a connecting rod |8|. The other end of this connecting rod is pivotally attached to a rod I82, Fig. 4, which is slidably mounted in a slot I88 formed in the arm 88. Secured to the end of the connecting rod |8I adjacent the rod I 82 is a plate I88 through which adiusting screws I88 pass and to each of which is connected one end of a coil spring I88. The other ends of the coil springs are attached to pin I81 affixed to the arm 88. The coil springs tend to urge the connecting rod l8| outwardly so as to rotate the lever I88 in a clockwise direction as viewed in Fig. 2.

Secured to the end of the rod I82 remote from the connecting rod 8| is a, bar I 88. To the outer end of the bar is secured a drum transport grab shoe slide I88. To the drum transport shoe slide I88 is secured a grab-shoe H8, which is asso-' ciated with a brake ring H2 secured to the inner periphery of the drum ring 88. Each of the lateral extending arms 88 on each of the arms 58 have rotatably mounted at its ends a tubular member H8. This tubular member has telescoped therein, as a' sliding flt, a tubular member H8. The tubular members H8 are slotted at H5 and through said slot extends a member H8 secured to the tubular member H8. The outer end of the member H8 is covered by an arcuate plate I", as clearly shown in Fig. 9.

The ends of the tubular members H8 are provided with cams I I8 which are adapted to engage with a cam plate H8 secured to the outer arm of the levers I88. The tubular members H3 and H8 are rotatable as a unit and when thus rotated the cams H8 rotate the lever I88 so as to move the connected rods |8| radially inward, thus moving the brake shoe H8 out of engagement with brake ring H2 and allowing the elements 88 to rotate as a unit free from engagement with the drum ring 88. By again turning the tubular members H8 and H8 the cam H8 permits the springs I88 to move the bar I88 radially outward to again bring the brakeshoe H 8 into engagement with the brake ring H2, and connecting the drum rims 88 thereto, whereby the drum rims 88 and the elements 88 are rotatable as a unit.

There is thus provided mechanism by which a compound or any movement may be imparted to the drum rims and the fabric 8| attached thereto. The operator controls the apparatus entirely by means. of the tubular members H8 and H8 in connection with the elements 88 and moves the entire assembly longitudinally along the I-beam l5 or transversely with respect to the spider 28 so as to bring the design outline on the fabric 8| into proper association with the sewing head II. By perfectly balancing the entire apparatus and levelling where necessary, and by properly adjusting the bearings so that no play is in the various parts, the operator can accurately control the device so as to correctly sew the design in the fabric 8|.

The design to be sewn on or in the fabric 8| may be marked on the fabric and the operator by proper manipulation brings each part of the design into association with the sewing device. The design may be sewn into the fabric 8| with silken or other thread and the design will be outlined by the sewn silk or other thread. In place of the silken or other thread to outline the design there may be utilized a cord, wire or other filamentary material, and in such case the filamentary material is encased in a tape, which tape is sewn to the fabric 6| and follows the outline of the design which may be marked or printed on such fabric 6|, or which may be followed by utilizing a template, or track. or similar device entirely separate from the fabric II and which controls the movement of the drum elements carrying the fabric II.

Where it is desired to outline the design with a cord, wire or other filamentary material encased in a tape, the head as heretofore designed will be insufficient for the purpose and, therefore, in this my present invention I have devised a new form of sewing head which simultaneously prepares and associates a filamentary material and a tape and encases the filamentary material in the tape, and simultaneously feeds the same to a point where the same may be sewn directly to the fabric 8|. Such a structure is illustrated in Figs. 13 to 17 inclusive, and referring t'o such figures there is shown a substantially circular plate I35 counterbored and internally threaded on its lower face to receive the threads of a bearing member I36. The plate I35 and member I36 form ball races for the balls of a rotary thrust bearing I31. The members I35 and I36 are screwed to the lower face of the head I1 by screws I39, as clearly shown in Fig. 15. Extending downwardly from and forming part of the head I1 is the needle bar I39 provided with a centrally arranged passage (not shown) in which is fitted the sewing needle I46, and which needle is held in position by the screw I. This needle bar I39 is in no way disturbed by the addition to the head I1 of the structure shown in Fig. 15. However, some slight modification must be made in the construction and operation of the presser-foot bar I42.

Secured to the rotary thrust bearing I31 by screws I43 is a hollow cylindrical member I44, in the vertical bore of which i rotatably and slidably mounted a hollow cylindrical member I45. The top of the member I46 is provided with a central orifice which forms a circular track I46. Track I46 is rotatably supported by a bar I41. The bar I41 is mounted on presser-foot bar I42 and is substantially arcuate in form so that the ends of the bar form'a diametrical line with the needle bar I39 as the center. The bar I41 preferably is provided with a bearing on each end (not shown) to reduce the friction of track I46.

The presser-foot bar I42, as shown in Fig. 16 may be the usual presser-foot bar with the presser-foot removed therefrom, or an entirely new presser-foot bar. In either event the lower end thereof is reduced in diameter and threaded as indicated at I48 to receive a nut I49 and such reduced end I46 passes through a perforation in the bar I41. After passing through the perforation in the bar I41 the reduced end I48 has 7 threaded thereon the nut I49 so that the cylindrical member I45 is attached thereto and is movable vertically with respect to the plate I35, and to the cylindrical member I44, while being capable of rotary movement in the cylindrical member I44 about the needle bar I39 as a center. By use of the usual presser-foot bar operating lever I56 the presser foot bar I42, the cylindrical member I45, and all parts carried thereby are moved upward and downward so as to bring the presser-foot or modification thereof into engagement with the fabric 6|, or the material to be sewed to such fabric 6|, and into operative association with the bobbin operating mechanism which is under the control of the sewing machine head 26. The cylindrical, members I44 and I45 are maintained in position on-the platform or plate In by means of uprights no, no, mounted on the four comers of said plate, as most clearly shown in Fig. 16, the upper ends of said uprights having inwardly extending finger portions I6I, I6I, engaging the upper faces or edges of the cylindrical unit I44.

Secured to, the end face of the cylindrical member I in any usual or desired manner is a presser-foot I5I, an annular plate I52 being interposed between the presser-foot I5I and the under surface of the-cylindrical member I45 for a purpose to be hereinafter described. When the lever I56 is operated to move the presserfoot I5I' intooperative association with the bobbin mechanism and with the fabric 8 I, the cylindrical member I45 may be rotated in the cylindrical member I44 and about the bar I41 without disturbing the relation which exists between the needle bar I39 and the presser-foot I6I and, therefore, it will be possible for thread to be utilized as the sewing medium by the needle I46 in all positions of the presser-foot I5I with respect to the needle bar I39.

For the specific purpose for which the present invention was developed I have provided a supporting framework which carries a filamentary material, such as a cord or wire, and an enclosing material, such as tape, and associated with such framework is mechanism which encases the filamentary material in the tape and simultaneously feeds the same into a groove on the under face of the presser-foot and into operative association with respect to the needle I46. This framework consists generally of a plate I53 substantially rectangular in form, and held against the lower face of the cylindrical member I45 by the annular plate I52 and the holding device for the presser-foot I5I. I preferably make the framework of relatively light material-to save weight and insure a working machine which will work accurately and easily without undue fatigue to the operator.

It will be understood of course that the rectangular plate I53 is provided with a centrally arranged aperture substantially equal in extent to the aperture in the cylindrical member I45 or to the inner diameter of the annular plate I52. Formed integral with the rectangular plate I 53 at opposite ends thereof and extending outwardly and downwardly are members I54 and I55 respectively. Formed integral with the members I54 and I55 respectively and extending outwardly and upwardly (see Fig. 13) therefrom are the members I56 from the members I54 and the members I51 from the members I55.

Because the material of the members I53 to I51 inclusive is relatively light I provide braces I56 as shown. The members I56 converge into a plate I59 and mounted on the upper face of such plate I59 is a rotatably mounted cylindrical holder I66 and on such holder I60 may be mounted a reel I6I carrying tape I62. The end of the tape passes around a pin I63 secured to one of the members I54 and thence through a guide I64 forming part of a folding and guiding means I65. The folding and guiding device I65 has its end terminating adjacent to the entrance of the passage on the under face of the presserfoot I5I, as clearly shown in Fig. 13.

The members I 51 converge into a plate I66 and on such plate and extending upwardly therefrom is a freely rotatable member I61 to which is secured a rotatable plate I88 provided with the upwardly spaced circumferential arranged arms I". Mounted on the centrally arranged member I81 is a reel I10 carrying cord or wire I" thereon. The cord or wire I'll passing from the reel I1! is led around a guide wheel I12 mounted on the member I55 thence around a guide wheel I13 mounted in a frame I14 mounted on the member I 54 and thence around a guide wheel I'll mounted in the same frame I13 and led into the folding and guiding means I65. The tape I" is led around the pin I83 into the folding and guiding means I" after which the Wire or cord III is led from the reel I10 and around the guide wheels I12, I13 and I14 into the folding and guiding means I65, care being taken to see that the wire or cord I1I is encased in the tape I" as clearly shown in Fig. 17. The encased cord or wire "I together with the encasing tape III is fed into the groove in the under face of the presser/foot ISI.

The entire structure described with reference to Figs. 13 to 17 inclusive is relatively light in weight and is so freely mounted for rotation within the cylindrical member I on the mem hers I 35 and I38 and so evenly balanced as to be freely rotatable in accordance with the movement of the fabric III which causes the presserfoot III to swing in accordance with the directlon of movement of the line of the design to be sewn on the fabric BI so that the wire HI and encasing tape I62 is alwaysfed out of the folding and guiding means I65 and through the slot in the under surface of the presser-foot II, and always in position to have the thread or the needle I pass through the overlapping edges of the tape I82 as clearly shown in Fig. 17. The operator is therefore enabled to easily and accurately follow the outlines of any design that may be marked upon the fabric 8|, or the device is capable of automatically following a design by means of a template and in this latter case it will be unnecessary to press the design or mark the fabric ll.

Whereas, I have described my invention by reference to specific forms thereof, it will be understood that many changes and modifications may be made without departing from the spirit of the invention.
